Speci-caton of Letters Patent. Application 1ed December 27, 1907. Serial No. 408,280.

Patented Dec. 14, 1909.

To all'whom 'it 'may concern:

Beit known that I, O'rro KRAUS, a citizen of the United States, residing at 169 West One Hundred and Thirty-sixth street, New York cit New York, have invented new and Ause l Improvements in Combustion- Chambers for Gas-Engines, of which the -following is a specification.

The present invention relates to combus- -tion chambers for use' with continuous combustion en 'nes of that type whrein the products o combustion are led from-'the combustion chamber to the working-cylinders of an engine.

The object of the invention is to provide a 'combustion chamber in which the fuel willbe .completely burned and to control theA temperature to prevent overheating of the casing and partitions located in the combustion' chamber, and to utilize the cooling medium for wer. I

My .inventlon is set forth in the accompanying drawing, which forms part of this specification.

In the drawing, I shows a longitudinal sectional view through the combustion chamber and feeding device in which A, indi cates a casting-of cylindrical form having an annular water chamber A', and a combustion chamber A2, in which are lqcated two perforated partitions BandB respec- 4 tively, between which isa bed of refractory material U,through the interstices of which the ases may pass from partition B to B'.

'I e perforated combustion chamber 'until it abuts againstthe shoulder H, formed by the reduced diameter of the chamber O. The refractory material is then inserted, and the perforated vpartition B' is then placed lin position as shown, the casting C abutting the edges of u same to hold it 1n position. Said casting C, is connectedto the chamber A, by stud bolts D and- D', andthe small end or outlet is adapted for engagementwith a pipe Ao r u l artition B', is located at. a predetermined dlstance from'the cover E,

the cylinder of an engine, as may be'desired. The opposite end of the chamber A is provided with a'cover E, which is removably secured thereto by stud bolts F and F', as shown, and the center of the cover E is provided with an aperture in which is located an atomizer G, which is secured to the cover by bolts H, as shown. A hollow cap J, is secured to the portion H ofthe atomizer and connected thereto is a pipe K, through which compressed air is led to the atomizer. A pipe R, controlled by a valve R', is connected tothe casin A, and in communication with the cham r A', and an outlet A3 is provided, which leads within the cham- .ber A2.

The chamber A' preferably extends the entire length of the combustion chamber, thereby completelysurrounding the same, so that water forced into said chamber will serve asa water jacket to prevent the overheating of -the walls of said combustion chamber. A pipe N, leads within and forms a part of the,at0mizer G, through which oil is supplied to said atomizer. The lower end' `of pipe L is clos'ed by any suitable means, but may be extended, if desired,to a chamber in which the fuel oil is stored to .conduct air from pipe K to the surface ofthe oil therein to force same through the pi e N to the atomiaerV G, as will be rendi y understood.

One of the'most important .points .js to d prevent the overheating ofthe perforated partitions .B andB, which may be made of cast iron or other suitable material, and I accomplish this as hereinafter set forth.

The' operation ,is as follows: Assuming air under a pressure of 50 ounds per square inch to be flowi'n throug pipe K and atomizer Gr, and oi to be flowing to the atomizer under the same pressure to pipe M and atomized improper proportions into chamber* O, the gases being ignited therein bythe spark plug L, which may be continuously operated,

' the heat thus generated will soon raise the re;

fractory material Uin chamber A2.to incuudcSCenOe, and therefore, to' prevent the heat from rising t a temperature suliicientlyhigh to injure the perforated partitions B and B' and the casing of the combustion chamber, water is forced to the chamber A through pipe R, by a pump or lother suitabI loo ilo

and steam fio'wing intotthe chamber' U is mixed with the products of combustion and serres for power in the engine cylinder, and

further by the steam or n'ater entering at.

the proper distance from the perforated partition B, the temperature ofthe saine is reduced belenv the melting or fusing pointof the materialfrom whichsaid partition B' is constructed, thereby protecting saine from injury, even though the refractory n'iaterial near the center of the combustion chamber was heated to a temperature above that necessary to cause such injury; The partition B isjprotected by causing thefmajor portion of the combustion of fuel gases to take place beyondsame and within the interstices of the refractory material U, ,the heat generated in chamber O being below that of the temperature of the refractory material U,

since the refractory material serves the fune tion of accumulating the heat and by reaction raising the temperature between the vertical dotted lines, to a point vmuch higher than that generated in' the chamber O.

It is obvious that gaseous'fuel may be fed direct through pipe K to chamber O, and the atoinizer dispensed with. It will be understood that any desired vpressure may be generated in the combustion chan'iber, limited only by the pressure at which the fuel is fed to the combustion chamber and the rapidity lwith which the gases generated thereby are drawn into 'the engine. ln ease the coin bustion chan'iber was disposed vertically, the top partition might be dispensed with; but preferably used to prevent small pieces of refractory material from' being 'carried into the engine, Ithe water and steam generated -serving to prevent thepassage ofsmall particles beyond this point. The refractory inat'erial ll serves to hold the heat and to effect the perfect burning` of the fuel gases, and in casey the gas :is shut ott forfan instant from 'flowing/to the combustion chamber, the refuel gases fed thereto. but do not fo-rin a part of the present invention.

llaving thus described .my invention, what l claim as .new and desire to secure by Lettersl Patent is- A combustion chambercomprising an ignition chamber; a second chamber-to hold coaiininuted refractory material having perforated retaining plates interposed across the patti of the combusted material; a. water jacket surrounding .said second chamber; a passage between said -ivater 'jacket and said set-end chamber. said passage located between the said retaining plates; suitable meansl to provide a continuous fion' of watertosaid picket; suitable. means to provide a flow of conductors to convey the heated gas and vapors away. i i

ln testimony i'vhereof, I have signed my fuel to said ignition'. chamber fand suitable l A,
